To all whom i'i 12mg/ concern:

Be it known that I, llifannnn Fenstern a citizen of the United States,and a residentV of Kenosha` county of Kenosha, and State ofW'isconsin',have invented certain new improvements in 'Spotlight Brackets, oflication. l

My invention relates to'improveinents in Y Yspotlight brackets and hasparticular reference to a bracket*which can iiionnted upon a wind shieldframe or other con venient part of a self-propelled vehicle and is soarranged that the' lamp supported thereby may be adjusted in anydesiredA position; l l

The obgects my invention are to pro` vide a bracket of the classdescribed which may 'be' rigidlyV and readily secured and mounted inplace on a vehicle, and which will be substantially .free from anytendency to become loosened orto move around on the support. A furtherobject `of theA invention is .to provide', in a bracket of the 'classdescribed, a universal. adjustment which will enable the lamp supportedby the bracket to be moved or rotated into any position yor direction atwill, and which, when uso adjusted in position, will permanentlymaintain its adjusted position withoutcany tendency for/'it to slewaround or become loose. A further object of the invention is to providean eflicient, neat, rigid7 and substantial bracket and `lamp adjustmentof the character' referred to.

A further object of the inventionxis to 'provide anlarrangement whichwill permit of convenient application of a subsidiary side light or acombined side and tail light,

and which will enable the leading-in wires shownin Fig 1*l certainportions of the casings being' :cut away in order to disclose theinterior construction;` y

Fig. 3 is aplan view ofthebracket, the laiiipshaving vbeen removedtherefrom;

V Figi 4; isfa front elevation of the bracket shown Fig. 3, `certainparts being shown in tsection which the following is a speci- .Fig 5 is'a section taken on the line 5 5` of Fig. and

Fig. 6 is an elevation of a part of the clamp. u Referring tothe"drawings.y it will be observed that l have selected asa support for thespot lamp, the side bar or frame 10 of the wind shield of theself-propelled vehi cle to which my improved bracket is applied. Thelamp 11 vhich is supported thereby, may be of any approved style,usually consisting of an outer casing l2 containing` a suitable electriclamp 13. It will be understood that the lamp 13 is located at 'the focalcenter of a parabolic reflector so that the lamp will throw asubstantially condensed or approximately parallel beam of light.` Y

The bracket is arranged toprojectlaterally of the wind shield member 10a sufficient distance to permit free movement of the spot lamp 11 inwhichever direction may be desired, so that the beam of light emanatingfrom the lamp can be thrown in all directions. Said bracket preferablycoinprises a laterally extending supporting portion 1st by means ofwhich the bracket may be clamped to the support 10. and an lL-shapedextension 15 the endof which is equipped with the necessary universaladjustment for supporting the spot lamp 11. l prefer to make theextensionarm 15 with twin spaced limbs, the space 16 between said limbsserving to accommodate and locate the supply cable 17 leading to thelamp. Said duplex construction of the arm 15 is also materially strongerthan in the case of al single arm and adds considerably to theappearance of the device.

"The means by which clamping of the bracket to the bar `10 is effected,comprise an inner clamping member 18 and `a pair of outer clampingmembers 19 and 2O which constitute bifurcations of the bracket. Saidparts 19 and 20 may be separate twin punchings as shown in the drawingsand at their outer ends are arranged with short turned down side flangesas at 21 the flanges being turned inwardly toward each other, as shownin Fig. E3 and being a suicient distance apart to tit snugly around abody part 22. Said body part 22 .may consist. of a.rectangu lar lblock`of brass or other suitable metal and hasat its inner end a transversenotch which accommodates a yoke or cross piece Q8. lt will he observedthat the end 'of the block j ing bar 10. Normally in applying` the clamp22 adjacent the supportingbar l() is pointed vor beveled orf to avoid apair ot clampingl bolts 24 by means ot which bolts the members 19 and 2Ocan be forced toward each suitable lock-,washers as shown at 26 :torpreventing impro perniorements of the nuts duel to the vibration of thesupport.

The arms 19 and 2() ot the clamp are snitably apertured; to admit therectangular cross piece 23 which extends loosely through said arms. Theends ot said crc-ss piece are tapped to receive a pair of parallel setscrews 27, the points ol which are` adapted to engage a pair of lugs 28extending from the inner clamping` member 18 and through suitableopenings` in the clamping' arms `VA19 i and 29. The openings throughwhich lugs 28 pass are formed by shearing ont ot the arms 19 and 2t) a.pair ot lugs 29 proiecing,l laterally trom the arms i9 and 2l) asellicient distance to bring` them substantially in register with thelngs. Preteralfly, when formingy the projections 29 on the arms 19 and20, `there is also formed a pair ci ribs 30 which constitute astrengthening bac-hing.; for the lugs 29. i i

It will be observed that thc arms 19 and 2() are `formed with. inturnedclamping; jaws as at 31 which jaws embrace and extend partially aroundthe inner side of the support-- to the said supperting` bar 10, thebolts 24- are tightened up as tar as is practicable and then the setscrews 2T which have previouslxr been slacked ol'l", are screwed home.4The etiiect `ot screwing up the screws 27 is twofold.. .ln the lirstplace, the inward Ifn'essure applied to the clamp member 18 muses the``edges 32 to 'forcibly engage the outside snrface of the supporting barl0. it xviii be ohserved that the clamp 18 is `made oi such shape thatthe edges 32 are spaced apart a substantial distance and are disposed-soas to contact with the bar 10 alone; narrow parallel spaced verticalZones ot considerable depth. In the second place'` the tightenin r up otthe set screws 2.7 has a tendency ti; flex the lugs l28 permitting saidings to contact with and bear strongly against the lnos L29 .whichproject from the arms 19 and, 20. This will result in a rockiifigaction, or atendency toward a rocking' action. ot the ends of the arms19 and 20,*and the jaw port-ions 31 will hence tend to approach'oneanother thereby exerting a pronounced and positive clamping action upon.the bar 10. l

The base block 22 is formed with an inte- :gral head vor lug 33centrally apertured to receive a clamping bolt 34 which is screwed lntothe base. 3570i the L shaped extension locked in a definite annularposition of ad.- I y n A g v jnstinent when the n lation oit the laacletis first effected.` the ciamp vbolt l l ing employedto loch the arm inthe beJr position to suit the particular arrangement of each indiyidnalinstallation. Ordinarily the claim;- ingportion 14 oit thebraclet andthe arm 15 are arranged. in line as lshown in Fire;

VThe lamp 11 is capable of being rotated around a horizontal axisandaround a vertical axis, both lmovements being with reference to the L`shaped extension arm 15 of the stationary or permanently adjusted.portion of the bracket. To this end I employ a socket member 39arranged intermediate between the outer or upper end 40 of the arm 15and the lamp 11 which is to be supported. Said socket member 39 isformed with a substantially cylindrical portion 41 having its'axishorizontal and is bored out to form a concentric cylindrical recess forthe reception ofsuitable friction clamping members. The said clampingmembers include a stem 42 the outer end oct which istormed with adisc-like head 43k slidably arranged in the inner end of the socket, itsouter surface engagging' a perforated friction disc 44. `Said frictiondisc 44 is Apreferablyv made of ber andis interposed liietweenthe head43 of the t said stein 42 and the bottom 45 oi the socket 41. rlfheinner vendv ot the stem 42 is threaded and is screwed into the upper end40 of the arm-"15, a lock-washerv 41? and lock nut 42 serving as meansfor permanently securing` vsaidstena 42 into the arm 15 and therebypreventing rotation of the sternin the .is applied to the washer 46,head 43 and friction disc 44 by means of an adjustable )lucF 48snrroundinw theA stem 42 and havin@ ha C t:

on its exterior threads49 fitting; correspfnnling,- threads formed inthe interior of the outerportion of the socket 41. In order to enablesaid plug 48 to be turned or adjusted to give more or lessffrictionbetween the Vsaid parts, I prefer to slot the outery face lt will beninlerstood that `the arm l5 is intended to be permanently ot the plugas shown at to accommodate a suitable wrench or spanner.

It will be observed that by reason of the movement of the `lamp.

The outer end of the member 39 is formed with Va, second socketdesignated as 51 similar to the socket 41, but having its axis at rightangles to the axis ot the socket 41, so that when the member 39 is inthe position shown in the drawings, the lamp maybe rotated around avert-ical axis. Said socket 51 isprovided with a friction mcmber'52 andadjustment plug 53 and a stem 54 provided with a head saidparts"Serf-.fingthe same purpose as similar parts contained within theVsocket 41.

The main spot lamp 11 is carried on the lower end of the stem 54 whichis made tunilar to provide a conduit 56 for the leading-in wires orcable indicated at 57, (see Figs. 1 and 2). The said stem 54 is alsoformed with an upper extension 58 which extends through a centralaperture in the friction washer 52 and through an aperture formed in thebottom wall of the socket 51. Both extremities of the tubular stem 54are threaded to accommodate lock nuts as at 59 by means of which thespot lamp 11 and auxiliary lamp 60 may be clamped on the ends of thestem. lt will be seen by reference to Fig. 2 that the ends of the stemare inserted respectively throuofh apertures in the upper wall of themain casing 12 and the lower wall of the casing of the auxiliary lamp60, the lock nuts 59 being disposed on either side of the wall ot thecasing. It will be understood that when the lamps 11 and 60 have beenonce properly locked or clamped to the ends ot the stud or stem 54, nofurther adjustment is required.

The main lamp 11 is equipped with a suit- I able handle 61 by means ofwhich the lamp may be swung around. a horizontal axis or vertical axis,or both, so as to direct the beam ot light toward any desired object. Itwill be understood that the friction adjustment plugs 48 and aretightened up to such an extent that enough friction is provided toprevent movement of the lamp due to vibration of the support. The shapeof the casing of the auxiliary lamp 60 is preferably cylindrical, theaxis oi the cylinder being located parallel with the axis of the mainlamp 11, and the ends of said cylinder are closed by a pair of lenses,one of said lenses, via, 62. being usually ot red `glass` and the frontlens 63 being ot' clear glass so that the auxiliary lamp 60 may serveboth as a tail light and as a front light.

The side of the auxiliary lamp casing 60 which teeds the main lamp 13 ism da may be made with a pairof glazed apertures `as "at 64, `casting asmall amount of lightI to the side of the kvehicle in order tofacilitate getting in or out of same.

Eis shown in the drawings, the cable taken 'trom the auxiliary lampconnector 65 where it is connected in multiple to the main supply wirel?. Usually, l. find it desirable to locate switch at the base o't themain iuinp whereby the main spot lamp may be switched oit while theparking light-60 is burning. Also in order to utilize the main lamp 13without consimiing current in the bulb G'Tlotthc parking light, thesocket 65 may be oit such construction that a slight `rotary movement ofsame will disconnect the supply circuit 'from the terminals ot the 'bulb67.
